CONCRETE CAR.

Application filed August 27,1920. Serial No. 406,379.

To all whom it may concern:

Be it known that I, JOSEPH B. STRAUSS, a citizen of the United States,residing at Chicago, in'the county of Cook and State of illinois, haveinvented a certain new and useful Improvement in Concrete Cars, of whichthe followingis a specification.

This invention'relates to concrete cars and has for its objectto providea new and improved device of this description. The invention has amongother objects, to provide a car having a concrete body formed to standthe strains andstresses and rough "uses to which cars are subjected, andwhich shall at the same time, be cheap to construct and comparativelylight in weight. The invention has other objects which are more clearlypointed out in the following. description.

' Referring now to the accompanying drawings which show the constructionembody ing my invention,

Referring now to 'the dra wiilgs, have;

shown a construction where areinforced concrete body is made separatefrom the metal underframe and is then placed upon this underframe andfastened thereto. The metal underframe may be of any desiredconstruction corresponding to that made by the Master Car Buildersspecifications. In 2 Figure 1, I have shown the body" made of reinforcedconcrete and having a bottonifl, and side walls 2, and ends 3. v Thebottom and side walls are preferably integral while the ends may beseparate and removably attached in position if'des'ired so thatifinjured, they can be easily replaced. The side walls are provided witha' series of ribs or stakes 1, which connect with the bottom and whichare provided with reinforcing metal 5. These stakes are both on theoutside and inside and" are shown in detail in Figure .6. There are;inclined ribs or stakes 6, which preferably connect with, the verticalribs or stakes 4, andwhich also contain reinforcing material. 7. Theupper edges of the body. are providedwith metal frame pieces 8 which areshown as channels and these metal frame pieces are connected to thereinforcement. In Figure 7, I have illustrated one method of doing thiswherein the reinforcing metal members 5 and 7 are connected "to theframe piece 8 by means of nuts 9. The stakes instead of beings-both onthe outside and inside may be only on one side as shown in Figure 5, andare provided with the reinforcing metal pieces 5. These reinforcingmetal pieces are tightened together by reinforcing metal 10. The bottomand sides have other metal reinforcement 12. I also prefer to providethe bottom, sides, and ends with wire mesh or net work reinforcement 13,and this reinforcement is connected with the longituddinal metal members8 at the top and let at the bottom of the side walls and ends. The metalunderframe is made up of the center sills 15 and bolsters 16, one ateach end and metal cross bearers 17. The concrete body has thelongitudinal metal members at the edges thereof and there are crossmembers 18 associated with the floor and connected with the longitudinalmetal members. This connection. is made in any desired manner asbyplates 19 and suitable rivets, and these cross members are alsoconnected with the longitudinal metal members 14 of the body by suitableplates 20. The center sills are preferably made up of metal parts asillustrated in Figures '3 and 12 and 13, although any other suitableconstruction may be used. The ends may be integral with the sides andfloor of, the body or they may be separate as'illustrated in F igure 2where y I have shown an end 22 having the upper and lower metal boundingmembers 8 and 14 and the stakes with the various reinforcing metal rodsembedded in the concrete. When separate ends are used, they are arrangedso that they may be removably connected with the wallsand bottom so thatthey can be disconnected for purposes of replacement. Suohends areprovided with limiting metal members on both thetop and bottom and theother edges, these other metal members being shown at 24. These metalmembers are removably connected to the side walls of the car by suitableconnecting pieces 38 as shown in Figures 1 and 21. I may also providepipes 28 for fluid which may be embedded in the floor of the car andextend longitudinally and cross-wise and- I can use them aspipes andalso "as reinforcing metal. These pipes may be provided for air andsteam. For exam'ple, at certain times, it is desirable to heat by steamwithinthe car and steam can be then sent through these pipes for thatpurpose. "In Figures 17 and 18, I have shown am'odified constructionwhere there is a metal longitudinal sill 30 and metal cross bearers 31and bolsters 32.

Figures 23 and 24 show the concrete door 39 with the metal boundingedges 40 and hinges 41. It will be noted I have here shown aconstruction of a concrete car comprising a metal center sill andbolsters, a concrete body comprisinga .fioor, longitu dinal metalmembers at the edges thereof,

cross members associated with said floor and connected to thelongitudinal metal members, reinforcement connected to the ;two sets ofmetal members, concreteembedding said reinforcement and containedbetween the longitudinal members, concrete sides and ends connected withsaid floor, said sides and ends comprising longitudinal metal members,reinforcement connected thereto and to longitudinal metal members of thefloor and concrete embedding said reinforcement and contained within thelimits of the longitudinal metal members, and cons necting means suchasthe plates 20 for connecting the concrete body as a whole to thecenter sill and bolsters. From the foregoing it will be seen thatapplicant has a metal underframe .and a concrete body having a floor andsides and ends of concrete. The body may beseparate from the underframe,and may be con? structed separate therefrom, and then placed on themetal underframe and connected therewith. It will further be seen thatthere are separate metalv members or connecting pieces'2O connectedwiththe bottom or floor of the body and by. means of wliich, throughsuitable bolts orthe like, thefbody is connected with the sills andbolsters] The cross bearers or cross members of the under frame may beattached to the longitudinal sill 30, as shown'in Figure 18, oiflmayibeseparate'from the center sill 15 and attached thereto by the fasteningplates 19 as shown in Figure 3. When this construction is used the crosspieces '18fmay be fastened to the center sill 15'before the bodyisplaced thereon, or they may be attachedto. the body by the connectingpiecesf20, and then fastened to the sill'15 after the body is placedthereon. Different forms of stakes are shown, the stakes projecting onone :side only being shown in Figure '5 and .the

stakes projecting on both sidesbeing shown.

in Figure 6. p v

Figures 1 and 4 show the body without the concrete cross bearers, whileFigure 19 showsv it with these cross bearers33f These concrete crossbearers will be used where desired and Omitted when it is not desired touse them.
